It is, but it looks like the UI is still enforcing the 3-drive minimum at the moment.

Not sure if a 3wZ2 will be allowed, but it’s in the same vein of logic as a 2wZ1 - create it now with more overhead (way more, in the Z2 arrangement) and then grow drive-by-drive with the new expansion.

I don’t think creating intentionally degraded arrays is going to be permitted; you’ll probably still be in the HERE BE DRAGONS camp on that.
